Rhythm. Normal cardiac rhythm arises from the SA node (sinus rhythm) but pacemaker impulses can come from ectopic foci in the atria, the AV junction, and the ventricles under abnormal conditions. When an ectopic impulse occurs singly, it generates a beat; when the beat repeats itself, it becomes a rhythm.
The Ksp value is calculated from the concentrations of the products of Ca(OH)2 when the compound is added to an aqueous solution. Calculating the value requires knowing those concentrations, the...

Next. Calculate the change in free energy (KJ) for the reaction NO(g) + O3(g) â NO2(g) + O2(g) under the following conditions: T = 298 K ÎGo = -198.0 kJ/mol Pressure of NO = 1.06 x 10-5 atm Pressure of O3 = 1.44 x 10-5 atm Pressure of NO2 = 2.50 x 10-6 atm Pressure of O2 = 2.25 x 10-2 atm.3 following. 1 answer. Report Abuse.nswers. Best Answer: use the formula delta G= -RTln K K=(partial pressure of NO2* partial pr of O2)/(partial pr of NO*partial pr of O3) R=8.314J.
